BELTFASTENER.

SPECIFICATION forming part; of Letters Patent No. 382.305. dated May 8. 1888.

Application tiled AMarch 10, 1888.

.To all whom it may concern:

Be it known that I, HENRY C. HERR, a citizen of the United States, residing at Villiamsville, in the county of Erie and State of New York, have invented certain new and useful Improvements in BeltFastenings,ofwhich the following is a specification.

My invention relates to machinerybelting and to a new and improved means for securing the ends of the belts together without the aid of lacing, and will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which--` Figure l is a face view of two pieces. of leather belting, showing the two parts having dovetailopenings and portions adapted to be put together and secured, as will be more clearly hereinafter shown. Fig. 2 represents two pieces of belting put together in accord ance with my invention. Fig. 3 is a longitudinal section through line (t b, Fig. 2. Fig. 4 is an edge View of a piece of belting pnt to gether and secured as shown in Fig. 2. Fig. 5 represents a back View of two pieces of belting put together as above described.

The end A of the belt to be secured together is provided with a series of dovetail openings, 2, putin by means ofa belt-punch ofthe proper shape for cutting such openings. This opera4 tion leaves a series of dovetail portions, 3. The bottoms 4 of the openings 2, it will be seen, are made slightly narrower than the smallest portions 5 ot' the parts 3. The other portion, B, (or other end ofthe belt,) is provided with a series of punch-openings, 6, and dovetail portions 7. These openings 6 and portions 7 are exactly of the same size and shape as the openings 2 and portions 3, the only difference being their position on the end of the belt, the smallest ends ofthe openings 2 on the piece A being opposite the center ofthe portions 7 on the piece B, so that while there are six dovetail portions 3 shown in the part A, there are Serial No. 266,888. (No model.)

In putting the ends A B of the belt together, I

the portions 3 are each pressed intothe openings 6, while the parts 7 are passed into the openings 2, and when all are in place, as shown in Fig. 2, a cord or wire, 9, is wound around the belt and the ends secured substantially as shown at 10 in Fig. 5.

Theobject in making the portions 5 a little wider than the parts 4 of the openings is to squeeze a little more material into the joint where the belt is put together, as in Fig. 2, than there is in the width of the belt, so as to make the joint capable of standing a little more strain than the rest of the belt. From actual test it has been found that other portions of the belt will break before the seam will separate.

The outer ends of the parts 3 and 7 should be chamfered off, as shown at 1l and l2 in Figsf 3 and `4. that this should bc done; but it improves the appearance of the joint without reducing its strength.

I claim as my invention-- 1. A belt for machinery having its ends united by a series of dovetail portions interlocked together and secured by a binding- It is not absolutely necessary 4 piece surrounding the interlocked portions of the belt, substantially as described.

2. In a machinery belt, the combination of the portion A, having a series of dovetail portions, 3, and openings 2 with the portion B, provided with a series of corresponding dovetail portions, 7, and openings 6, the whole interlocked together and secured with a bindingwire, substantially as described.
